the guy pulling a cliff claven with the "who is the Russian dog" answer was great.
I thought the same thing! "Who are 3 people who've never been in my kitchen?"
About a year or so ago, I heard Dan Patrick's name as a possibility to host. Speculation that he'd never do it immediately following Alex's passing, but maybe a few years down the road.
I like Ken Jennings, but I think he talks and reads the clues too fast.
Personally, I wouldn't mind seeing a series of unknown guest hosts chosen from auditions, just like contestants are.
